Characterizing Flotation Response: A Theoretical and Experimental Comparison of Techniques
… flotation behavior. These procedures, known as release or tree analysis, generally involve multi-stage flotation in batch, laboratory flotation cells using various combinations of rougher, cleaner, and scavenger configurations. Although some of these procedures have been experimentally compared, …

Processing of high-sulfur coals using microbubble column flotation
… was characterized using a technique known as "release analysis". This technique was used to provide the optimum grade versus recovery relationship for a given coal and a given set of reagent conditions. It was also used as a means for evaluating the various schemes for rejecting coal pyrite. …

Development of Methods to Aid in Flotation Circuit Evaluations and Drip Pan Design
… known as StackCell flotation. Flotation release analysis was performed on all samples to determine the amount of hydrophilic material present in the streams around the flotation cell. Data from this work supported recommendations from the equipment manufacturer that the wash water …

Model-Based Control of Gasoline Partially Premixed Combustion
… use of in-cylinder pressure sensors. Online heat-release analysis is used for the detection of the combustion phasing and the ignition delay that function as combustion-feedback signals. It is shown that the heat-release analysis could be automatically calibrated using nonlinear estimation …

Characterization of knocking combustion and heat transfer in a spark ignition engine
… by several knock indices, based on the net heat release analysis of cylinder pressure, as well as, the amplitude of the knock induced pressure fluctuations. Knock initiation and development were investigated by sampling cylinder pressure data at two different locations in the chamber. The cyclic …

An In-Plant Evaluation of Froth Washing on Conventional Flotation Cells for Coal
… liquid mass balances), salt tracer studies, and release analyses. The data collected from these tests have been used to develop criteria that describe when and how froth washing may be successfully applied in industrial flotation circuits. A second series of tests was developed to look at other …

Laminar flame propagation in a stratified charge
… technique and flame speeds were measured by heat release analysis of the pressure data. An one-dimensional, time-dependant numerical simulation of the flame propagation in a charge with step-stratification was used to interpret the experimental results. Both the experimental and numerical studies …

Evaluation of column flotation circuits for fine coal cleaning
… the maximum separation curve predicted using the release analysis technique. Also, the simulated results in almost all cases predicted better results than what was actually obtained. This discrepancy was attributed to the inability of the rate-based model to adequately describe restrictions …

Parametric study and simulation of microbubble column flotation
… below the ideal separation curve predicted by release analysis, provided that a sufficient bias flow was maintained. The test results also demonstrated that various combinations of operating conditions can be utilized to achieve the same level of metallurgical performance. In order to develop …

Managing transient behaviors of a dual mode spark ignition-- controlled auto ignition engine with a variable valve timing system
… rich condition during transient operation. Heat release analysis has been conducted to characterize the combustion process in CAI mode. Large variations of the 50% burned point due to fluctuation of residual gas mass and temperature were observed. Small step changes in valve timings (EVC, EVO, …

Management and Analysis of Localization Information in Uncrewed Aerial Systems
… UAVs and cooperative swarms. First, we present a release-by-release analysis of 3GPP’s evolving support for UAVs from LTE Release 15 through 5G-Advanced Release 19, highlighting architectural, radio, and sidelink mechanisms that enable identification, 3D tracking, command-and-control, and …

Precombustion Removal of Hazardous Air Pollutant Precursors
… work, along with trace element float-sink and release analysis data, were used to develop a simulator that can predict trace element rejections from any coal processing circuit. This was achieved by applying general partition functions to trace element washability and bench-scale processing …
